Title: Radar apparatus
Inventor: INOMATA NAOFUMI
IPC: G01S7/40
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain a radar apparatus that can detect instantaneously a failure when the failure which cannot obtain a beat signal is generated irrespective of whether an object exists or not on radar transmission-reception waves, and obtain further a failure-detecting method. SOLUTION: In the radar apparatus having a transmitting-receiving antenna 4 which is excited in a set band, an oscillator is oscillated at a frequency which is excited in a measurement, and at a frequency which is not excited. Thereby, at the nonexciting frequency, reflection is generated due to the impedance mismatching of the antenna, and a DC component is generated from a mixer 5. As a result, when the radar apparatus is normal in the diagnosis of a failure, the output of the mixer becomes a state that the DC component is increased. When a failure that the output is cut off in, e.g. a transmission system, the DC component is reduced, and the failure can be detected by comparing the DC component with a set threshold value.

Filed: 1989-06-20
Abstract: PURPOSE:To prevent the generation of a bird's head at the time of the formation of an element isolation oxide film and the formation of a polycrystalline semiconductor oxide film by previously shaping a third oxidation-resistant film onto the sidewall section of a trench formed to a semiconductor base body and the side face of a first polycrystalline semiconductor layer on the island region of the semiconductor base body. CONSTITUTION:A first pad oxide film 104 under an 'overhang' is removed, the inwall of a trench 108 and the side face of a first polycrystalline silicon film 106 are thermally oxidized, a second pad oxide film 109 and a first polycrystalline silicon sidewall oxide film 110 are shaped respectively, and a third silicon nitride film 111 is deposited on the whole surface. The second pad oxide film 109 is exposed only on the base of the trench 108 through anisotropic etching to the third silicon nitride film 111. An isolation oxide film 112 is formed in the trench section through oxidation treatment while using a first silicon nitride film 105, a second silicon nitride film 107 and the third silicon nitride film 111 as masks. No bird head is shaped in island regions 103a, 103b at that time, and a first polycrystalline silicon film 106 is not oxidized.

Abstract: PURPOSE:To decrease the operation cycle of an RAM, by separating a bootstrap capacitance of large capacity from a common data line at the time of leading edge of a word control signal, and at the same time precharging it with other MISFET during boosting. CONSTITUTION:A MISFETT51 applying a power supply voltage vcc to the gate is provided between an output line of a pulse generating circuit phix-GENE provided on a common word line and a connecting point N1 in a booster circuit phix- BOOS, a bootstrap capacitance CB21 is given between connecting points N2, N1 to which a pulse signal phipad delayed for the leading time from the word line control signal phix, and an MISFETT52 the gate of which is a voltage of N1 is applied is provided between the output line and a connecting point N3 respectively. A CB22 between the N2 and N3 is precharged at the reference potential signal level period of the pulse signal at the N2 with a switching element T53 between the N3 and the power supply voltage Vcc. Thus, since the CB22 of comparatively large capacity is separated from the common data line at the time of leading edge of the phix, the leading speed of the phix is quickened and the operation cycle of an RAM is shortened.

Title: Excess spin-loop shunt device for multi-processor-system
Inventor: JIEEMUZU KURIFUOODO DARII
IPC: G06F11/00
Filed: 1989-06-20
Abstract: PURPOSE: To make it possible to easily exit from an overspin loop by automatically detecting the overspin loop and making a recovery, and preventing recovery operation from being applied to a routine which is inadequate for the recovery operation. CONSTITUTION: When detecting a 1st processor being in a spin loop state wherein a resource held by a specific routine of a 2nd processor is requested for a predetermined time, a detecting means specifies an object processor as an object of corresponding recovery operation. A processor by-pass indicating means employs a 1st indication value when a specific routine to which the recovery operation is not applied is executed by the processor and indicates a 2nd indication value in other cases, and at this time, the resource held by the object processor is released. Consequently, a read spin loop state is distinctly discriminated and an effective mechanism for recovery from the overspin loop state can be obtained.

IPC: G01S5/10
Filed: 1979-12-04
Abstract: PURPOSE:To perform phase calibration with simple circuits by phase-synchronizing the intermediate frequency signal output and the VCO output indirectly via a voltage control phase shifter by using one VCO. CONSTITUTION:When changeover switches S1 and S3 are changed over to calibration, a VCO7 stores and holds the frequency and phase just before the changing- over. A voltage control phase shifter 31 receives the output of a phase discriminator 6 of a master station receiving channel via a DC amplifier 32 and a low-pass filter 33 and the output thereof is applied to the phase discriminator 6 via a mixer 29, a pulse shaper 30, the changeover switch S1, a high frequency amplifier 2, a mixer 4 and an intermediate frequency amplifier 5. Hence, the phase shift quantity of the voltage control phase shifter 31 is controlled by the output of the phase discriminator 6 so that the output of the phase discriminator 6 becomes zero in the final, that is, so that the phase difference between the output of the VCO7 and the output of the intermediate frequency amplifier 5 is kept at 90 deg..
